Investigating the Geochemistry of Selenium (Se) in the Residual from Biological Wastewater Treatment

Although selenium is an essential element for human and animal health, it has a narrow concentration range before becoming toxic. Industrial practices, such as mining, can result in elevated levels of selenium to be introduced into surface water bodies, hence, treating mine processing water and wastewater is commonly done to reduce the potential for environmental impacts. Bacterially mediated redox processes are currently used in the mining industry to remove selenium from wastewater. The byproduct of this treatment is a solid state residual which contains high concentrations of selenium.

Fugitive lead emissions study for the Trail smelting operation

Teck Metals Ltd. operates one of the world’s largest integrated lead-zinc smelting operations based in Trail, British Columbia. An important part of Teck’s normal day-to-day operations is to carefully track and report on any pollutants generated on site that are released into the environment. The purpose of this internship is to assist their Company in estimating atmospheric emissions of lead particulates from a variety of sources.

Performance of cavity nesting birds breeding on reclaimed mine tailings

This study will assess the behaviour, physiology and reproduction of individual birds breeding on reclaimed mine tailings, and will provide a robust measure of the effectiveness of reclamation efforts on the Highland Valley Copper operating area.

China’s Western Development Program in Inner Mongolia, Gansu, Qinghai and Xinjiang

Throughout the 1980s and 1990s, while coastal ‘Special Economic Zones’ and ‘Open Cities’ flourished in eastern China, western regions still languished in relative poverty.

An Inverse Gaussian plume approach for estimating zinc emissions from a smelting operation.

Teck Metals Ltd. operates one of the world’s largest integrated lead-zinc smelting operations out of Trail, British Columbia. Every year, they report on atmospheric emissions of zinc and other contaminants through Environment Canada’s National Pollutant Release Inventory (NPRI). The purpose of this internship is to extend an existing inverse Gaussian plume model for estimating the emissions of zinc from point sources. The input to the algorithm is a collection of measurements of particulate material deposited on the ground in the area around the Trail smelter.

Evaluation of the Effect of Air Sparging on the Performance of Industrial Copper Electrowinning

As part of a program to improve the profitability of operations at Quebrada Blanca, Chile, Teck is testing an air sparging system in their industrial copper electrowinning cells. This represents a unique opportunity to measure the effects of gas sparging on product quality and metal production cost, and to generate a predictive model to help optimize the operation of electrowinning cells employing gas sparging.
